## Introduction to Data Interpretation

#### Data Interpretation

Direction: The bar diagram given below shows the productions (in the unit of thousand pieces) of three types of biscuits by a company in the five consecutive years. Study the diagram and answer the following questions.

1. The percentage drop in the number of glucose biscuits manufactured from 1994 to 1995 is

1. From the given bar diagram , we see

 Required percentage drop = 30 - 22.5 × 100 30

##### Correct Option: C

From the given bar diagram , we see

 Required percentage drop = 30 - 22.5 × 100 30

 Required percentage drop = 7.5 × 100 = 25% 30

1. The total income exceeds the total expenditure over the years 1982 to 1986 by

1. On the basis of given graph in question ,
Total income = \$ 240 lakh
Total expenditure = \$ 155 lakh
∴ Required Difference = Total income - Total expenditure

##### Correct Option: A

On the basis of given graph in question ,
Total income = \$ 240 lakh
Total expenditure = \$ 155 lakh
∴ Required Difference = Total income - Total expenditure
∴ Difference = 240 – 155 = \$ 85 lakhs

1. Percentage increase in profit in 1986 over 1982 is

1. According to given bar graph , we have
Profit in 1986 = 25
Profit in 1982 = 10
Increase = 25 - 10 = 15

 Required percentage increase = Increase × 100 Profit in 1982

##### Correct Option: A

According to given bar graph , we have
Profit in 1986 = 25
Profit in 1982 = 10
Increase = 25 - 10 = 15

 Required percentage increase = Increase × 100 Profit in 1982

 Required percentage increase = 15 × 100 = 150% 10

1. The ratio of the average income of all the years to the average profit is

1. From the given bar diagram , we see
Total profit of all the years = 10 + 20 + 10 + 20 + 25 = 85
Number of years = 5

 Average profit = \$ 10 + 20 + 10 + 20 + 25 lakhs 5

##### Correct Option: B

From the given bar diagram , we see
Total profit of all the years = 10 + 20 + 10 + 20 + 25 = 85
Number of years = 5

 Average profit = \$ 10 + 20 + 10 + 20 + 25 lakhs 5

Average profit = \$ 17 lakh
∴ Average income = \$ 48 lakh
Required ratio = Average income : Average profit
Required ratio = 48 : 17

1. The number of years in which the income is more than the average income of the given years is

1. On the basis of given graph in question ,
Total income of the given years = 30 + 50 + 40 + 60 + 60 = \$ 240
Number of years = 5

 Average income = \$ Total income of the given years lakhs Number of years

 Average income = 240 = \$ 48 lakhs 5

##### Correct Option: C

On the basis of given graph in question ,
Total income of the given years = 30 + 50 + 40 + 60 + 60 = \$ 240
Number of years = 5

 Average income = \$ Total income of the given years lakhs Number of years

 Average income = 240 = \$ 48 lakhs 5

In the years 1983, 1985 and 1986, the income were more than the average income.
